How Animation Works

The magic of moving pictures

1

Persistence of Vision

Your brain holds onto images for a fraction of a second. When images change fast enough, they blend together into smooth motion.

Animation
Frame: 1/8
Fun Fact

Your brain retains each image for about 1/25th of a second. That's why movies at 24 frames per second look smooth!

2

Frame Rate (FPS)

Frame rate is how many images show per second. More frames = smoother motion. Movies use 24 FPS, games often use 60 FPS.

24 FPS
Moving Circle
24 FPS - Standard film rate since the 1920s. Smooth enough for most motion, with a "cinematic" feel.
Fun Fact

Some gamers can perceive differences up to 144 FPS or higher! High refresh rate monitors make fast games feel incredibly smooth.

3

Onion Skinning

Animators use "onion skinning" to see previous and next frames as ghost images. This helps them draw smooth motion between poses.

Fun Fact

The name "onion skinning" comes from the old days when animators drew on thin paper called onion skin, which was translucent enough to see through!

Animation Fun Facts

🎬 Disney's "Snow White" (1937) used 250,000 hand-drawn frames
🎮 Video games often run at 60 FPS for responsive controls
📽️ The first animations were drawn on cave walls 5,000+ years ago
⏱️ 1 second of animation = 12-24 individual drawings
